Sherman argues that the Pirates prove that point — they had been rebuilding for years before they finally reached the playoffs last season, but this season they’re struggling yet again. (Even the Pirates’ playoff year depended heavily on outside additions A.J. Burnett, Francisco Liriano, Russell Martin, Jason Grilli and Mark Melancon.) Highly-touted young players like Pedro Alvarez don’t always gradually improve as projected, just as Ike Davis (now a Pirate) did not gradually improve with the Mets. Still others, like Matt Harvey, undergo significant injuries. Sherman argues that building the core of a team through one’s farm system is not without risk. Here are more notes from the National League.

The Las Vegas 51s have announced that the Mets have optioned top prospect Rafael Montero back to them. Montero made four starts for the Mets, posting a 5.40 ERA with 7.7 K/9 and 5.0 BB/9 in 20 innings. The move clears space for the Mets to promote fellow pitcher Buddy Carlyle. The Mets will replace Montero in their rotation with Daisuke Matsuzaka, as Mike Puma of the New York Post tweets.

Pablo Sandoval “belongs in San Francisco,” and the Giants ought to work out a new deal with him before he’s eligible for free agency this fall, the San Francisco Chronicle’s Bruce Jenkins writes. Not only is Sandoval a popular player, Jenkins argues, but his positive outlook helps in the Giants’ clubhouse. Also, the Giants’ relative lack of organizational concern about plate discipline makes the team a good fit for the free-swinging Sandoval. Jenkins thinks the Giants might be able to get a five-year deal with Sandoval done before the All-Star break.
